I'm Nikola Jeremić - certified NASM coach, former pro athlete, and someone who has lived every high and low of performance, injury, and comeback.

Over the past decade, I trained under elite coaches, played across multiple countries, and faced physical and mental setbacks most people never see. I've rebuilt myself from the ground up - more than once. What I discovered is this: your body can't go where your mind won't follow.

That's why I created a system that helps people like you build not just a better physique - but a stronger mindset, better habits, and the kind of confidence that stays with you for life.

Whether you're an ambitious professional, a parent looking to get back in shape, or someone who's just tired of starting over - I bring you the discipline, structure, and clarity of a high-performance life.

Let's build a body that performs and a mindset that never quits.

Let's make this transformation the last one you'll ever need.

My mission is simple but powerful:

To inspire people to believe in their own potential and create a life they are proud of - through fitness, discipline, mindset, and purpose.

I believe fitness is not a phase. It's a lifestyle, a foundation, and a daily ritual of self-respect.

That's why I created Ragukai Fitness - a movement, not just a coaching service.

With years of experience and a deep understanding of body mechanics, fat loss, muscle building, and performance, I create personalized programs tailored to real people and real lives.

No fluff. No BS. Only what works.

MY WHY

To lead by example and help others break their limits.

HOW

By combining science-backed training, real nutrition, accountability, and mindset work.

WHAT I OFFER

Premium coaching tailored to your goals, lifestyle, and identity.

Whether you want to look insane on the beach, feel confident shirtless, or move and perform like an athlete - I'll get you there.
